The oil in my cranckcase is getting more by every ten hours. I've seen in the forum that i'm not the only one thats having this problem.
Are there any situations known where this problem is solved ?
It's a f115 yamaha.
Have also seen rising oil levels in Honda 50 4str. Think its fuel thats getting in somewhere. Did notice when trailing that we store the engine on the wrong lock. We noticed a little label that said when trimmed up, this side up!!
I've no idea about that particular engine but fuel in the sump is often caused by the diaphragm of a mechanical fuel pump being perforated and this allows fuel to pass through.
